FloodFillCommand Class

Performs a flood fill on an image. You can use it to fill an area of an image surrounded by FillColor by setting Mode to Edge, or you can fill the pixel color at Position with FillColor.

public class FloodFillCommand : ImageRegionCommand, 

The FloodFillCommand type exposes the following members.

Public methodFloodFillCommand
Creates a new instance of FloodFillCommand.
Protected methodFloodFillCommand(SerializationInfo, StreamingContext)
Creates a new instance of FloodFillCommand from serialization information.
Public methodFloodFillCommand(Point, Color, Double, ColorMatchMode)
Creates a new instance of FloodFillCommand specifying the position, fill color, tolerance and color match mode.
Public propertyApplyToAnyPixelFormat
Reports whether or not this command will be applied to any supplied PixelFormat image
(Inherited from ImageCommand.)
Public propertyCanApplyToAnyPixelFormat
Returns true if the command can be applied to any PixelFormat.
(Inherited from ImageCommand.)
Public propertyFillColor
Gets or sets the Color used for the fill.
Public propertyInPlaceProcessing
Gets a value indicating if the source image data is processed in-place as opposed to returning a new image.
(Overrides ImageCommandInPlaceProcessing.)
Public propertyMode
Gets or sets the ColorMatchMode used for the fill.
Public propertyPosition
Gets or sets the X, Y pixel position where the fill should start.
Public propertyProgress
Gets or sets the ProgressEventHandler delegate which can be used to view or cancel the progress of the current process.
(Inherited from ImageCommand.)
Public propertyRegionOfInterest

Gets or sets a RegionOfInterest which will only process the indicated region of the image.

(Inherited from ImageRegionCommand.)
Public propertySupportedPixelFormats
Returns an array of PixelFormats supported by this command.
(Overrides ImageCommandSupportedPixelFormats.)
Public propertyTolerance
Gets or sets the percentage of color variation.
Public methodApply
Apply the command to the given image.
(Inherited from ImageCommand.)
Public methodApplyToImage Obsolete.
Applies the command to the source AtalaImage.
(Inherited from ImageCommand.)
Protected methodConstructChangedSourceImage
The method is called by the default implementation of Apply. It determines if it is necessary to create a copy of the source image in a different pixel format and if so, determines the best new pixel format and allocates that image.
(Inherited from ImageCommand.)
Protected methodConstructFinalImage
Called by the default implementation of Apply, ConstructFinalImage constructs the image that will be used as the destination image for the command.
(Inherited from ImageCommand.)
Protected methodConstructImageResults
Constructs the results object for this command.
(Inherited from ImageCommand.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Protected methodGetChangedPixelFormat
This method is called to change the pixel format of the source image.
(Inherited from ImageCommand.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetObjectData
Fills the SerializationInfo object with information for this command.
(Overrides ImageRegionCommandGetObjectData(SerializationInfo, StreamingContext).)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodImageCommandGetObjectData
Aggregates ImageCommand data into the supplied SerializationInfo object.
(Inherited from ImageCommand.)
Public methodIsPixelFormatSupported
Returns a value indicating if the specified pixel format is supported.
(Inherited from ImageCommand.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodPerformActualCommand
PerformActualCommand does the actual work of the image processing command.
(Overrides ImageCommandPerformActualCommand(AtalaImage, AtalaImage, Rectangle, ImageResults).)
Protected methodSelectBestAlternatePixelFormat
Choose the best pixel format to use for this command when the supplied source image's pixel format is unacceptable.
(Inherited from ImageCommand.)
Protected methodSelectPreferredPixelFormat
Chooses a pixel format that is preferred for this command.
(Inherited from ImageCommand.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Protected methodVerifyImage
Verify the integrity of an AtalaImage.
(Inherited from ImageCommand.)
Protected methodVerifyProperties
Verify the integrity of properties in the command before processing an image.
(Overrides ImageCommandVerifyProperties(AtalaImage).)

This command requires one of the following image formats:


If any other image format is passed, you will receive a System.ArgumentException.

FloodFill Example (C#)
Rectangle rc;

if (this.viewer.Selection.Visible)
    rc = this.viewer.Selection.Bounds;
    rc = new Rectangle(Point.Empty, this.viewer.Image.Size);

Point pos = new Point(rc.Width / 2 + rc.Left, rc.Height / 2 + rc.Top);
FloodFillCommand cmd = new FloodFillCommand(pos, Color.Red, 5, ColorMatchMode.Surface);
cmd.RegionOfInterest = new RegionOfInterest(rc);

FloodFill Example (Visual Basic)
Dim rc As Rectangle

If Me.viewer.Selection.Visible Then
    rc = Me.viewer.Selection.Bounds
    rc = New Rectangle(PoInteger.Empty, Me.viewer.Image.Size)
End If

Dim pos As Point =  New Point(rc.Width / 2 + rc.Left, rc.Height / 2 + rc.Top) 
Dim cmd As FloodFillCommand =  New FloodFillCommand(pos, Color.Red, 5, ColorMatchMode.Surface) 
cmd.RegionOfInterest = New RegionOfInterest(rc)
